EESI advocates for the sale of E15 (15 percent ethanol, 85 percent gasoline) in New York State, arguing that it improves air quality and reduces greenhouse gas emissions compared to E10. The document highlights that E15 reduces volatile organic compound (VOC) emissions and displaces toxic "gasoline aromatics" like the BTEX complex, which are linked to cancer. It also notes that E15 does not increase tailpipe emissions or damage catalysts in older vehicles and contributes to a reduction in transportation-sector greenhouse gases, with corn ethanol being on average 43 percent less GHG intensive than gasoline.

• Increasing ethanol content from E10 to E15 reduces harmful volatile organic compound (VOC) emissions, lowers smog-forming potential, and cuts greenhouse gas emissions. It specifically displaces the BTEX complex (benzene, toluene, ethyl-benzene and xylene), which has high cancer-causing potential.
• The transition from E10 to E15 results in a 6.6 percent decrease in the cancer risk of 1-3 butadiene, although it increases the cancer risk associated with acetaldehyde by 1 percent.
• Testing by the National Renewable Energy Lab (NREL) on vehicles from 2000 and 2009 with 120,000 to 170,000 miles showed that E15 and E20 blends did not increase tailpipe emissions compared to ethanol-free fuels, nor did they damage vehicle catalysts.
• Domestically-produced corn ethanol is on average 43 percent less GHG intensive than gasoline. Increasing the blend from E10 to E15 represents an additional 1.5 percent reduction in GHG emissions.
• Cellulosic ethanol, which must be 60 percent less GHG intensive than gasoline under the Renewable Fuel Standard, can reduce GHG emissions by 90 to 115 percent relative to gasoline depending on the feedstock.
